Brian, the Griffin family’s talking dog, died during Sunday’s episode after he was hit by a car. The decision to kill Brian off came up in the writers room and was seen as a fun way to mix up the show. The show has already replaced Brian with another talking dog named Vinny, who is voiced by The Sopranos’ Tony Sirico. Seth MacFarlane, the creator of Family Guy, is a huge fan of The Sopranos and wanted to do a character based off of Sirico’s voice, reports CNN.

Family Guy fans aren’t taking Brian’s death sitting down. One fan has already started a petition on Change.org asking the show’s creators to bring Brian back. The petition’s goal is 50,000 signatures and it already has over 48,000 signatures. The petition also links to a Facebook (FB) page titled “R.I.P Brian Griffin from Family Guy” that has over 600,000 “Likes.”
